Sleep deprived parents like myself who could stand to loose a few pounds just got one more excuse. Apparently researchers at the University of Chicago have found that chronic sleep loss may actually increase your appetite. So if "I just don't have enough time to exercise," or "It's not my fault if I unwittingly tried to keep up with my pregnant wife's increased caloric intake" don't quite have the same punch that they used to, now you can really blame the baby.
